Collagen acidic ph triple helix
WebAug 19, 2024 · Collagen mimics are peptides designed to reproduce structural features of natural collagen. A triple helix is the first element in the hierarchy of collagen folding. It is an assembly of three parallel … WebA collagen-like peptide with the sequence (GER)15 GPCCG was synthesized to study the formation of a triple helix in the absence of proline residues. This peptide can form a triple helix at acidic and basic pH, but is insoluble around neutral pH. The formation of a triple helix can be used to covalently oxidize the cysteine residues into a disulfide knot. Three …
